To all whom t 'may concern.' i

Be it known that I, BALB lV. AMMONS,

a citizen of the UnitedStates, and a resident of Los Angeles,county of Angeles-,State c of California, have invented a newand usefulV Leaf-Spring Lubricator, of 'which the following is a sp'eciiication. l

This invention relates toA devices foriu-I bricating leaf springs of'v automobiles and' l() f other vehicles. r u v vThe principal objects fof my invention are to provide means v'for easily and `quickly spreading the leaves 'of the springs, and means for injecting oil or grease Si'nto th.e space between tlrejleaves. 'A-lso, a-.device lwhichinay be brought from an inoperat-ive to an 'operative position `with a single move- Y nient of a lever, 'and a deviceivhich ,may be whichmay be considered as shown approximately full size for onel sizeofvmyy device, l

'Y but which vis made inavariety of sizes;

Figure 2 is a of Figure 1;

Figure 3 is an of Figure 1; .Y .v

Figure 4 is a plan view ofthe lever handle of-my device. j' f Essentially my invention consists of a levered device-for forcing apart the leaves plan View of the upperrpart end view of the upper part of a leaf spring, anda lubricating nozzle leg and directed arranged for injection of grease in the space. .v

The device takes the lforni of an L-shaped bracket 1 havinga wedge shaped spreading jaw 2 extending from the end of the short parallel to the long-leg` oftheL. j, j Y

The long legY is slotted at 3 and has ratchet notches t formed Valong bothy sides of the ,slot to selectively" engage the teeth,

5 of a bearing portion 6 adjustable along the 'slot into thevarious notches and locked in place by a 'nut 7 bearing against the under Y side of theV bracketfand threadedly engaging an extension 8 from the bearing portion wherebyy the bearing portion may be drawn Figure .1 is an elevation of my device andl An operating 'shaft 9 is revolvably lsup;- portfedin the lbearing portion and carries atits upper end a cai-n disk sp'ringfspreader The spreader 10 is adisk eccentrically se'- riveting it to a squared. for' flat-tened vend of the'sha-ft orby holding it 'onen-chal squared Y end 11-by means offfa potten-pin 12jas ini `f dicated. n 4The edge ened at the portion of. leastv extension 13 and `gradually 'llattened atfthe point Eof greaterthrow 14 and the diskfis aligned with the lfixed spreadingwedge 2, thus presenting in use a Vrota-ry wedge for forcing the springs apart upon turning *the shaft@ "about -ah'alf revolu'tioi'i, fthe' thick edge'llnioving freni 'the dotted positionatvtlrevleft' V"to" the full line position'jaty thefrigh't as indica-ted. in

The' vehicle spring would take 'a j josition between the j aw'2' and the spreader disk 10 and in order to introduce grease or oil into the space between the leavesy of the spring after spreading apart, a' hole 16 extends through thel aw EZ-coming out at the lower side ofthe bracket where itis either simply threaded as shown at 17, or provided with a standard pressure lubricator connectionl'S.

In forming this hole to comeout at the under ,sideV of the bracket, it would ordinarilybe 'drilled at right anglesu and the portion 19 plugged as indicated. The operating shaft 9extends a Vconsidn Y erable distance below the bracket at the side opposite 'from which the spreading def vicesarelocated and is preferably ofhexa-VV Y tightlyvagainstthe'npper'sideof the bracket'.l 'A i *or cinepresa@ disk-issn@- ouf gonform 9V throughout the exposed por-l tion so as to provide for the engagement of along the shaft, while the other end of the handle-'has a wrench socket 21 to lit the nut'( for adjusting thebearingportionin lthe slot.

f The provision of a long extension operating shaft under the bracket as Well as the provision so that the wrench handle may be slid' to anyk point along the shaft, is onevr a socket wrench handle 20 at any point Vof the'most vimportant featuresof my in,`

vention, for the spring suspension varies so much in different automobiles that a deviceV which cannot be operated Vfrom underneath,

or in which the handle isV lixedwill often l be found useless'` on `account of interfering frame constructions,-brake rods, braces and other features, Whereas With my device the operating shaft extends vertically down one side of the spring and the handle may be w vthe spreader' disk..

slid along it to dodge lany constructional feature of the particular automobile being Worked upon. j v Another feature of importance is thetermination of the oil hole or grease gun connection 18 under-*the bracket for this keeps the grease line Within the bracket Width vso it Will not be broken by interfering parts mentioned ,and also vprovides for much more convenient operation of greasing devices attached to the opening. j v

In (use, my device is placed over kthe spring and the lever given a'lialf turnland a shot of grease injected through the nipple Withfany formV of gun. If the gun has a flexible tube it may be left connected to the nipple in changing fro-mono leaf to another. y

Y Having thus describedniy invention and its Inode of use,

I claim: L l. A leaf spring spreader comprising a bracket, a Wedge jaW projecting from one side of the bracket, a shaft-*extending entirely through. the' bracket and revolvably supported thereongwhile projecting from both sides thereof, a spreader disk eccentricallysecured to the shaft onthe jaw side of the bracket adaptedtofcooperate With the` jaW for spreading a leaf spring, the extension of the shaft on the other side of the bracket being accessible for revolving 2. A leaf spring spreader comprising a bracket, a Wedge jaw projecting from one side `of the Y bracket, a shaft extending through the bracket and revolvably supported thereon, a spreader ,disk eccentrically secured to the shaft on the jaw. side ofthe bracket adapted to cooperate with the jaw'pfor spreading a leaf spring, 'the evtens sion 'of the shaft `onthe other side of the bracket being accessible for revolving the spreader disk andAk having a VWrench en-jV gaging portion formed therealong.

3. A leaf spring spreader comprising any L-shaped bracket having a spring prying Wedge on the short arm and a slot inthe long arm, a bearing `member adjustable along the slot and provided with a nut for clamping it to the long ar1n,'a shaftextending through the bearing member and slot-ajcircular Wedge .secured tothe end of the shaft alignedA with the said Wedge 'for prying a spring upon turning the shaft, and

Va Wrench handle for the shaft having a vportion vadapted to engage theshaft extension for turning it and also a portion adapted to engage the said nut for Vvturningit.
